The working principle of the epitaxial furnace is to deposit semiconductor materials on a substrate under high temperature and high pressure. Silicon epitaxial growth is to grow a layer of crystal with the same crystal orientation as the substrate and different thickness on a silicon single crystal substrate with a certain crystal orientation. This article mainly introduces the silicon epitaxial growth methods: vapor phase epitaxy and liquid phase epitaxy.

​In the silicon carbide (SiC) PVT crystal growth process, the stability and uniformity of the thermal field directly determine the crystal growth rate, defect density, and material uniformity. As the system boundary, thermal-field components exhibit surface thermophysical properties whose slight fluctuations are dramatically amplified under high-temperature conditions, ultimately leading to instability at the growth interface.

In the era of rapid MEMS (Micro-Electromechanical Systems) evolution, selecting the right piezoelectric material is a make-or-break decision for device performance. PZT (Lead Zirconate Titanate) thin-film wafers have emerged as the premier choice over alternatives like AlN (Aluminum Nitride), offering superior electromechanical coupling for cutting-edge sensors and actuators.

In the high-stakes world of semiconductor manufacturing, where precision and extreme environments coexist, Silicon Carbide (SiC) focus rings are indispensable. Known for their exceptional thermal resistance, chemical stability, and mechanical strength, these components are critical to advanced plasma etching processes. The secret behind their high performance lies in Solid CVD (Chemical Vapor Deposition) technology. Today, we take you behind the scenes to explore the rigorous manufacturing journey—from a raw graphite substrate to a high-precision "invisible hero" of the fab.

During the SiC epitaxial growth process, SiC coated graphite suspension failure may occur. This paper conducts a rigorous analysis of the failure phenomenon of SiC coated graphite suspension, which mainly includes two factors: SiC epitaxial gas failure and SiC coating failure.

With the development of the solar photovoltaic industry, diffusion furnaces and LPCVD furnaces are the main equipment for the production of solar cells, which directly affect the efficient performance of solar cells. Based on the comprehensive product performance and usage cost, silicon carbide ceramic materials have more advantages in the field of solar cells than quartz materials. The application of silicon carbide ceramic materials in the photovoltaic industry can greatly help photovoltaic enterprises reduce auxiliary material investment costs, improve product quality and competitiveness. The future trend of silicon carbide ceramic materials in the photovoltaic field is mainly towards higher purity, stronger load-bearing capacity, higher loading capacity, and lower cost.
